Media take-up on/off sensor
The photointerrupter-based media take-up on/off sensor detects the switch status of the media take-up unit.
When the media take-up switch is set to ON, the sensor arm transmits the sensor light, power-on the media take-up unit.
When the media take-up switch is set to OFF, the sensor arm shields the sensor light, shutting down the media take-up unit.
Media take-up paper detection sensor
When the sensor light is shielded by a loop of printed paper, the media take-up motor rotates to take up the paper.
